Regions

You can add the following line after your builder initialization but before sendRequest.

[builder setRegionID:@"1337"];

The following example will add regional information to a Home request:

RCHRequestPlacement *placement = [[RCHRequestPlacement alloc] initWithPageType:RCHPlacementPageTypeHome name:@"<placement name>"];
    
RCHPlacementRecsBuilder *builder = [RCHSDK builderForRecsWithPlacement:placement];
// Add region information
[builder setRegionID:@"1337"];

 __block RCHRecommendedProduct *product;
[[RCHSDK defaultClient] sendRequest:[builder build] success:^(id responseObject) {
    RCHPlacementsResult *result = responseObject;
    RCHPlacement *placement = result.placements[0];
    product = placement.recommendedProducts[0];
} failure:^(id responseObject, NSError *error){
    // Use this code block to handle any errors that may occur while loading recommendations.
    NSLog(@"Error encountered: %@", error);
}];
